A weak engine oil pump can show up as a low oil pressure light, a low gauge reading or engine noise. A clogged oil filter, a faulty oil pressure sensor, a low oil level or worn engine bearings can be behind these signs too, so track down the cause before you buy a pump. A shop can test oil pressure for you.
